Linearization of low noise amplifier for wireless sensor networks

This paper designs a Low Noise Amplifier (LNA) used in RF front end receiver system for wireless sensor network applications. The proposed LNA adopt post distortion technique. This Low Noise Amplifier provides a low noise figure of 2.14 dB with a forward gain of 16.6dB. The LNA circuit consumes a power of 11.6mW for 1.8V supply. The circuit is implemented using 180nm CMOS technology.
